Marcus solved for x in the quadratic equation x2 - 10x + 25 = 0. x = x = x = What is true about Marcus's work? Check all that apply. Marcus should have substituted - 10 for b, not 10. The denominator should be 1, not 2. Marcus should have subtracted 4 (1) (25) in the square root. This equation, when solved correctly, only has 1 real number solution. This equation has 2 real number solutions.
